Peer Mentoring in the General Chemistry and Organic Chemistry Laboratories Caleb A. Arrington, Jameica B. Hill, Ramin Radfar, David M. Whisnant, and Charles G. Bass
This article describes a discovery experiment in which organic chemistry students act as mentors to general chemistry students. Members from both groups work together to isolate an unknown compound using distillation. The structure of the product is then determined collaboratively using IR and NMR spectroscopy.

Analog Spectrophotometers in the Digital Age: Data Acquisition on a Budget Alexander Y. Nazarenko and Natalie A. Nazarenko
In this article we describe how to employ an inexpensive analog-to-digital converter and a user interface to Microsoft Excel to make a useful computerized spectrophotometer. Readily available types of data loggers, Vernier LabPro and digital multimeters with an RS-232 interface, were utilized. The proposed design does not compromise the quality of the measurements. The conversion of the data to the Microsoft Excel format makes it a convenient tool for a wide range of data processing applications.

Turning on the Light: Lessons from Luminescence Patricia B. OHara, Carol Engelson, and Wayne St. Peter
The goal of this article is to provide secondary school science teachers with a background in an array of luminescent phenomena including fluorescence, phosphorescence, and chemiluminescence that will enable them to teach their students fundamental properties of light and matter. Instructions for building and operating a simple spectrofluorometer and five detailed lesson plans are provided in the Supplemental Material for experiments that utilize these processes.

The Singlet States of Molecular Oxygen Jean-Pierre Puttemans and Georges Jannes
Although the purpose of the article The Visible Spectrum of Liquid Oxygen in the General Chemistry Laboratory is an analysis of the two-moleculesone-photon absorption spectrum of oxygen, it nevertheless assigns arrangements of the electrons in an energy diagram to the two singlet states of molecular oxygen which do not seem to be correct in our opinion.
